Theory analysis showed that the method of two-position alignment increases the observability degree of state variables, especially for the error of accelerometer and azimuth misalignment.

理論分析結果表明黄色片在线播放又大又粗又爽无遮挡，兩位置對準可以提高系統(tǒng)狀態(tài)變量的可觀測度，尤其對加速度計誤差和方位失準角的可觀測度提高作用明顯韩国精品毛片2019。

In order to solve the problem, in this dissertation, a new IA technology based on wavelet-filtering and two-position alignment is proposed. The useful signals of sensors are gained by wavelet filtering; the error angles, constant drifts of FOGs and biases of accelerometers are computed through signals at two positions.

The thread form and helical angle of screw are key factors that influence the screw-in ability of a bolt and reliability of screw coupling. There exist significant correlation between them, therefore the contour of thread portion can be used to judge the acceptability of a bolt.

牙形和升角是影響緊固螺紋通過性和接觸可靠性的重要因素免费午夜性爱视频，它們之間存在良好的相關性，通過檢測緊固件螺紋部分的輪廓線的形狀和位置可以判斷其通過性和接觸可靠性免费在线免费A片。

The lift course of hanging device on wheat no-tillage planter was simulated by using the software of ADAMS. Some important parameters were obtained such as height of the working part relative to ground, the distance between the working part and the rear wheel of tractor, the angle of road pass and the force of hanging point, etc. The key parameters of the hanging device and its best working parameter of hanging device were found out through optimization simulation. Simulation results showed that suspension point had minimum force when variable DV_1 and DV_2 gained corresponding maximum and minimum at scope of structure limit.
